Trash trackers: The secret life of garbage

What happens to your garbage once you send it out into the world? Enter our exclusive competition to find out.

New Scientist has teamed up with researchers from MIT's SENSEable City Lab to launch the British arm of their Trash Track experiment. If you live in the UK and would like to get involved, go to www.newscientist.com/projects/forms/trash and tell us, in no more than 75 words, what you would like to tag and why. The best suggestions will win a tag and the chance to follow the trail of your trash.

The results of this unique experiment will feature in a forthcoming issue of New Scientist magazine and on newscientist.com.
